1 Claim. (Cl. 98-88) This invention relates to a combined mountingmemher and drainage channel. It deals more particularly with a combinedmounting member and drainage channel for use with ventilators adapted tobe inserted into an opening in a wall or a sloping roof of a building,such ventilators being hereinafter referred to as ventilators of thekind described.

It is an object of the present invention to provide a combined mountingand drainage channel which will secure the ventilator in position in thewall or roof of a building without allowing the entry of rain water intothe building.

It is a further object of the invention to provide a mounting member toenable a stock size ventilator to be mounted in a water tight manner ina range of opening sizes.

It is astilI further object of the invention to provide an improveddrainage means for ventilators.

With the above and other objects in view, the invention will behereinafter more particularly described and the arrangement of themounting member and ventilator will be shown in the accompanyingdrawings and pointed out in the claim.

Now referring to the drawings:

Fig. 3 is a section on the line IIIIII of Fig. 1 to an enlarged scale,and showing the position of the ventilator in the aperture in the wallof a building.

Fig. 4 is a section through the bellows and winding gear shown in Fig.3,

Fig. 5 is a detail view,

Fig. 6 is a side sectional elevation of a combined fixing, mountingmember and drainage channel. constructed in accordance with the presentinvention, Fig- 7 is a fragmentary perspective view taken fromunderneath in the direction of the arrows on the line VII'-VII. of Fig.l and showing part of the ventilator to which the combined mountingmember and drainage channel has been attached.

According to the embodiment illustrated in Figs. 1 to 5 of the drawingsthe ventilator comprises a box like frame or housing 2 forming theventilator opening, the housing 2 having a flat fascia frame 4 at thefront or interior of the building longitudinal sides 6 normal to thefascia frame 4 are provided with flanges 8 for the whole-of theirlength, said flanges being at right angles to the sides 6 and parallelto the fascia frame 4. The fascia frame 4 cornprises a pair of spacedparallel combined mounting and drainage channel members 76 and a pair ofspaced parallel transverse upper and lower walls 29 and 32 respectivelyand described below in greater detail. The attachment of channel members76 to the upper and lower walls is effected by any of the well knownmeans e.g. bolts and rivets and is considered to be a matter of designonly. Secured to or formed integral with these flanges 8 are upstandingnarrow ribs 10. Said ribs 10 in the form shown are formed of a singlethickness of sheet metal folded back and turned up at right anglesto theflanges 8- and are pierced by holes 12 at intervals along their lengthto receive and journal the hinge rods 14 running across the frame 2. Tenlouvers 16 are hingedly mounted on rods 14 inserted in the holes 12.Said louvers 16 are each formed from a single sheet of metal longer thanit is wide and approximately shaped so that it can be formed by apressing operation. The longitudinal edge of the louver sheet adjacentwhich the hinge is to be formed is bent over to form a double thicknessprojection 18 the corners of which are cut away for Vsth inches on eachside of the louver so that the projection 18 clears the flanges 8 byabout /eth inches on each side. The longitudinal free edge of the doublethickness projection 18 is bent up into a circular section beading 20adapted to receive the hinge rod 14, said beading 20 being approximately%th inch from the double edge of the projection 18 and running paralleltoit. The other longitudinal edge of the louver is shaped into' aninverted serni circular trough or channel 22 which faces in the oppositedirection to the beading 20. Each of the transverse edges of the louveris formed with a slightly tapered trough 24 running from the hingebeading 20 to beyond the trough 22, said troughs 24 facing in the samedirection as the trough 22 and having their larger diameters adjacentthe trough 22. Where each tapered trough 24 meets the trough 22 asemi-circular piece- 26' is cutaway from it to allow one trough tocommunicate with the other.

Said louvers are mounted: on the hinge rods 14 in the narrow ribs '10with their hinged edges lowermost. A louver bracket 28 is riveted orotherwise secured to each louver 16- near the trough 22. Each saidlouver bracket 28 is provided with a hole at its free end adapted forloose connection with a linking control bar 30. Said con trol bar 30' isformed from a single sheet of metal bent to a narrow U and drilledthrough at spaced intervals by holes 31', the free ends of the brackets28 being riveted in the holes 31 in the U in such a way that the controlbar 30 canbe moved relative to the said brackets 28.

The transverse lower wall 32 is formed as a trough and provided with adrain aperture 90. Furthermore, lower wall 32 is provided with anextension 34 which extends below the ends of the ribs 10 and carries a Ushaped shield 36 bolted to it by a bracket 38. The upper end of the Ushaped shield 36 is embraced by a bracket 40 bolted to the flat fasciaframe 4. The shield 36 is square in cross section and forms a cover fora chain hereinafter described. A worm screw 41 inside the casing 42 isworked by a control knob 44 to drive the said chain into the shield 36when the knob is turned. The stiff section of the chain is protected bya bellows 46 and is secured to an end member 48' pivotally mounted onthe control bar 30 by the securing screw 52'. A two armed spring 50 ismounted on the securing screw 52, the end of said spring 50 being turnedover the end member 48 and the bar 30 so that they always exert adownwards pressure on the end member 48.

The ventilator is adapted to be recessed into thewall or sloping roof ofthe building in which it is to be incorporated and to be secured thereinin a manner to be hereinafter described with the flat frame 4' flushwith the interior surface of the wall and the hinges of the louverslowermost. When the louvers are open they are substantially horizontaland the chain is fully retracted into the shield 36. As the control knobis turned the chain feeds out into the bellows 46 and pushes the louversup to the closed position. In the closed position the troughs 22 and 24on each louver engage partly around the hinging beads 20, the upstandingportions 10 of the flanges 8 and the upper ends of the troughs 24 of theadjacent louvers immediately above them. In this way any rain whichfinds its way into the hinges of the louvers when they are closed willbe carried across into the troughs 24 and will run down them past theextension 34 into the trough formed in the bottom wall 32 from which itwill drain away through the drain aperture 90 provided above thedownwardly outwardly sloping ledge of the aperture in the wall of thebuilding as shown in Fig. 3.

Referring now to Figs. 4 and 5 the said chain is of the type in whichthe links 56 are provided with abutments 58 and with teeth 60 forming arack on one side of the chain. Thus in one direction the chain can onlybe slightly arched and will then form a stiff rod which can be used totransmit a longitudinal thrust whilst in the other direction the chaincan be freely flexed. The rack formed by the teeth 60 on the one side isadapted to cooperate with the worm screw 41 which thus forms a drivingmeans for imparting a thrust to said chain. Since the two-armed spring50 is always urging the end member downwardly the chain links 56emerging from the casing 42 will always be arranged in a slightly archedmanner to form a stiff rod.

Now referring to Figs. 6 and 7 there is shown a portion of the side ofthe frame of the ventilator 2 having a side wall 6 formed with aninwardly turned flange 8 defining the ventilator opening to the exteriorof the building and a short outwardly directed flange 72. The side wall6 of the frame 2 is provided with a re-entrant joggle 74, the

depth of which is equal to the thickness of the metal of which thehereinafter described flange is formed.v The combined mounting anddrainage channel member 76 is made of sheet metal and comprises a shortfirst flange 78 adapted to fit the joggle 74 in the side wall 6 of theside frame 2, whilst being supported on the flange 72, and

secured to the wall 6 by rivets 80; an outwardly extending portion 82 atright angles to the first flange 78 and parallel to the flange 72, saidportion 82 having the dimension A of a standard width i.e. 1" or 2" or3" as required, to fit a window frame of the selected range of aperturesin which the ventilator may be fitted; an upstanding swage 34 oftriangular cross section provided in said outwardly extending portion82; a back turned channel extending the length of the inside of theventilator, and communicating with drain aperture 90 through lower wall32 above the sloping ledge of the aperture in the wall of the buildingso that water in the ventilator drains out thereof onto said slopingledge and thence to the exterior face of the building.

The said mounting member 76 is of the same length as the side frame andthe double thickness portion has an overall width A depending on thewidth between the glazing bars or other opening defining elements of thebuilding. The joint between the first flange 76 and the side frame 2 atthe joggle 74 does not necessarily need to be water-tight since even ifwater does penetrate the joint it merely flows into the drainage channeland out onto the sloping ledge provided at the aperture in the wall ofthe building.

The joggle 74 provided in the side frame wall 70 allows the outside wall70 of the ventilator side to present an unbroken appearance and this toa certain extent prevents water collecting there.

With this type of combined mounting member and drainage channel as abovedescribed I have found that ventilators can be made in standard unitsand interchangable mounting members fitted to any unit according to thedesign of the building and the supports for the mounting members, and.in this way the setting up of special tools is avoided.

Having thus described one embodiment of the invention, it is to beunderstood that the mounting member and drainage channel is susceptibleof modifications such as may be obvious to anyone skilled in the art andthat the embodiment disclosed is descriptive and not to be construed aslimiting the scope of the invention.

Again it is to be understood that the materials from which the mountingmember may be manufactured and herein defined in the specification andclaim as metal clearly indicates materials which are capable ofsupporting the weight of the ventilator and of withstanding the weather,such as plastics and plastic covered metals and even thin wood.

What is claimed is:
